In an Instagram post on Thursday, Camila announced she would be joining Project HEAL, a nonprofit organization that helps people with eating disorders pay for treatment. The Riverdale star opened up about how eating disorders have affected the lives of those nearest and dearest to her, and shared that she knows firsthand how hard they can be. "Could not be happier about my decision to get involved with Project HEAL," she wrote. "I can say from experience that eating disorders are serious mental illnesses. Growing up, I watched my big sister suffer from one for many years, and I've experienced periods of my life when I've suffered symptoms as well."

Camila continued by saying one Riverdale fan could spend a day on set for helping to support Project HEAL's efforts. "I'm joining Project HEAL to help break the stigma associated with eating disorders," she wrote. "I'll be attending their SF Gala at Levi Stadium on Saturday, and auctioning off a day on the Riverdale set. Please, please, please join me in supporting this incredible organization."

Since she uploaded the post, Camila has received a huge outpouring of love and support from her fans. Some had experienced eating disorders themselves and thanked her for letting them know they weren't alone. "This just made my day," wrote one user in a comment. "I’ve had an eating disorder for a while, and it’s rough. Support from u makes me so happy thank u so so much."

Others pointed out how important it was for organizations like Project HEAL to help people get the treatment they need. "I'm so glad there's light being shed on eating disorders," commented one user. "I've got one, recovery is an absolute struggle and with low awareness there's barely any services to go to. Thanks for speaking out about it Camila."

Like with other mental illnesses, there's a lot of silence, stigma, and stereotypes surrounding eating disorders. Media depictions of eating disorders can easily trigger someone with an eating disorder or recovering from one, and movies like To the Bone have been criticized by some viewers for seeming to romanticize eating disorders. Meanwhile, seemingly innocuous things that we're surrounded by all the time, like "before and after" photos and talk about vacation weight gain, can also perpetuate dangerous myths or shame about the illness.

As the National Eating Disorders Association points out, although 30 million Americans will experience an eating disorder at one point in their life and it has the highest mortality rate of any mental illness, most people aren't getting the help they need. It's very commendable that celebrities like Camila, Demi Lovato, Kesha, and Troian Bellisario are using their platforms to break this silence and start changing the narrative.
